We welcomed back Dr. Jim Logan, Dr. John Jurist, and Dan Adamo for a 1 hour 45 minute discussion about humans to Mars and a critique of the  “NASA’s Journey to Marts: Pioneering Next Steps in Space Exploration (Oct. 2015).”  Please note that our program completed in one long segment without a break.  We started off by asking Dr. Logan to summarize the recent New World Space Conference he attended in Austin, Texas.  Jim pointed out that there were lots of young students there and they seemed eager to hear his message and did not consider him a Debbie Downer.  Jim is an evidence based guy when it comes to space policy and programs, he is also well grounded in the sciences and engineering so he does not typically hang out in the usual space cadet la la land of make believe.  We noted that older, more seasoned space cadets often dismiss those with similar messages based on evidence and fact,  but Jim was impressed by the willingness of the younger group to consider evidence and facts. The other guests plus myself had much to say about this particular issue, then we moved on to Dan who wanted to talk about the paper he has uploaded on TSS blog containing his analysis and comments re the NASA Journey to Mars Document. If you have not yet read it, please do so at this time.  For Dan and our guests, there were issues about a poorly defined definition for exploration vs. pioneering, confusing the two in the Journey to Mars document, the need for congressional action to change the mandate to pioneering, then asking for the rational for pioneering or Martian settlement. Much was said about there being no business case or rational case at all for humans to be on the surface of Mars.  This was an overriding theme for the entire discussion.  Our guests kept asking the question, “why are we doing it.?  This referred to humans on the surface of Mars for pioneering purposes.  Note the definitions Dan used for exploration and pioneering earlier in the show.  Note also the differences Dan suggested for exploration.  Our guests talked about the challenges that make Martian settlement or pioneering beyond our reach at this time.  Dr. Jurist brought up radiation and microgravity issues along with other human factor issues.  Dr. Logan supported what John was saying and called for the need to know the gravity prescription.  Without knowing it, we cannot possibly be serious about sending humans to mars.  Our guests talked about nuclear thermal propulsion and several times they referenced the Aquarius Concept (www.spaceenterpriseinstitute.org/tag/aquarius-concept).  Cognitive decline was also discussed as a leading challenge.  The matter of the Twin Study on the ISS with astronaut Scott Kelly came up.  Jim said a sample size of one does not help as it would only lead to insufficient information.  Our guests talked about radiation shielding, its cost, and added mass.  Dan mentioned a recent Aviation Week article from a September issues saying that nuclear propulsion may have a timeline for development around 2022-24.  John had much to say about this.  John also brought up the economy, potential interest rate rises and the impact on space and NASA. Jim said we needed a 10% growth rate for our interplanetary work.  We addressed the economic issues for several minutes as it was an important part of our discussion.  Later, I mentioned the recent interest I was seeing from Space Show listeners regarding the pioneering of Venus with some sort of settlement in the upper atmosphere. Our guests pointed out the pros and cons for this & we contrasted it with pioneering on the surface of Mars.  Joe sent in an email asking for the action plan or steps to be taken to pioneer Mars.  Don’t miss how our guests responded to Joe’s question.  This provided the opening for more discussion about cislunar development.  Here, our guests had much to say, including rescue opportunities, the lack of a redundant vehicle in contrast to even Apollo 8. Dan talked about this issue in technical terms so don’t miss it.  Near the end of the program, SLS came up but in the context of problems with it regarding mass, the stages, Orion, abort and rescue, black zones and more.  Don’t miss what Dan had to say about SLS and technical problems and issues.  The issues Dan raised are not the typical issues one hears discussed when talking SLS.

Please post your comments on TSS blog.  You can reach either of the three guests through me at drspace@thespaceshow.com.

We welcomed back Dr. Stan Rosen and for the first time, Dave Dressler, ISDC 2013 Chair, to talk about the upcoming ISDC 2013 event to be held in La Jolla, CA from May 23-27,  and much more.  For more ISDC 2013 information, visit their website, http://isdc.nss.org/2013.  To find out more about the NSS and join, visit www.nss.org.  During our first segment of this 1 hour 44 minute program, Dr. Rosen focused on the reorganization of NSS management and programming, NSS membership, and other changes having taken place in the organization.  Dave then started explaining the logistics for the conference including hotels and conference registration, plus the available tours in the San Diego region per conference arrangements and reservations.  As for ISDC 2013 content, I asked about social events and we talked about the Saturday night costume (your choice) party and the networking plus open bar before each evening meal/program.  During this segment, Dave went into detail about the tours one can go on when registered for the conference. We also talked about ISDC PR, local San Diego media, and much more.  We highlighted key speakers and scheduled events.  You can see the list of all the speakers confirmed to date at  http://isdc.nss.org/2013/speakers-all.shtml.

In our second segment, we talked about specific sessions and speakers based on the Confirmed Tracks page on the ISDC website, http://isdc.nss.org/2013/tracks.shtml.  As you can see and hear, topics covered this year are cutting edge space development, commerce, policy, and exploration topics.  We highlighted a few of the tracks including Asteroids, Breakthrough Science & Advanced Space Technology Concepts, Emerging Space Applications, SSP, the NSS Roadmap, and Transhumanism.  During this segment, the 7th grader I have spoken about on other programs sent me his list of interview questions which I read on the air as an example of why we need NSS and others in terms of education outreach.  Both of our guests and a caller talked about the questions plus how best to carry out space education outreach for all grade levels to adults.  We talked more about the big Saturday evening party, the band, and the social networking of the event.  Our two guests each provided us with closing comments.

If you have any questions/comments, please post them on The Space Show blog.  If you want to email either of our guests, do so through me at drspace@thespaceshow.com.

We welcomed Yonatan Winetraub as our guest to discuss SpaceIL, Israel’s Google Lunar X-Prize entry.  Mr. Winetraub founded SpaceIL through an interesting set of experiences and conversations at a local Israeli establishment.  He tells us this interesting story as we begin our one hour discussion. At age 26, Yonatan proves that much can be done with passion, commitment, education, volunteers, and local industry support.  During our discussion, Yonatan told us about the SpaceIL plans, the lunar hopper that they will land on the Moon, and their process in procuring a secondary launch contract for the launch capable of putting their lander on a trajectory to the Moon and landing in time to win the Google Lunar X-Prize contest.  One issue we discussed in detail was the fact that their secondary payload would have propulsion on board making it challenging to be approved as a secondary payload by the primary payload on the launcher.  In fact, Charles both emailed and called at the end of the program to raise the propellant issue for secondary payloads.  SpaceIL as a nonprofit, is also engaged in STEM and education outreach in Israel and this too was a significant part of our discussion.  Yonatan got questions about commercial space and space attitudes in Israel and the treatment of their venture by the Israeli general public and press, both in Israel and internationally.  The Google Lunar X-Prize competition was discussed as well as their funding and plans for after the contest ends. Given that SpaceIL is consulting with American companies, we talked about our ITAR laws as well as the Israeli ITAR laws and regulations.  The SpaceIL website is www.spaceil.com and I urge you to follow along on the site while listening to this discussion.

If you have comments/questions for Yonatan Winetraub, please post them on the blog and I will call them to his attention.  You can also email him through drspace@thespaceshow.com.  We will certainly be talking with Yonatan again as they progress in the competition.
